The current study explored whether a multidisciplinary family-based intervention underpinned by self-determination theory could enhance perceptions of parent need support, autonomous motivation, and quality of life in overweight and obese adolescents. Using a staggered-entry waitlist-period control design, adolescents (n = 56) were assessed at baseline and preintervention (within-participant control), immediately following intervention, and at 3, 6, and 12 month follow-ups. Parents were trained in need-supportive behaviors within the broader context of an 8-week multidisciplinary intervention attended jointly with adolescents. Following intervention, significant improvements were demonstrated in adolescent perceptions of parent need support, autonomous motivation, and quality of life, and changes were maintained at the 1-year follow-up. Mediation analyses revealed changes in perceptions of parent need support predicted changes in quality of life indirectly via changes in autonomous motivation. Findings suggest overweight and obese adolescents are likely to benefit from multidisciplinary family-based interventions that aim to train parents in need-supportive behaviors.

This study examined the association of autonomy-related variables, including exercise motivation, with psychological well-being and quality of life, during obesity treatment. Middle-aged overweight/obese women (n=239) participated in a 1-year behavioral program and completed questionnaires measuring need support, general self-determination, and exercise and treatment motivation. General and obesity-specific health-related quality of life (HRQOL), self-esteem, depression, and anxiety were also assessed. Results showed positive correlations of self-determination and perceived need support with HRQOL and self-esteem, and negative associations with depression and anxiety (P<.001). Treatment autonomous motivation correlated positively with physical (P=.004) and weight-related HRQOL (P<.001), and negatively with depression (P=.025) and anxiety (P=.001). Exercise autonomous motivation was positively correlated with physical HRQOL (P<.001), mental HRQOL (P=.003), weight-related HRQOL (P<.001), and self-esteem (P=.003), and negatively with anxiety (P=.016). Findings confirm that self-determination theory's predictions apply to this population and setting, showing that self-determination, perceived need support, and autonomous self-regulation positively predict HRQOL and psychological well-being.

Background Studies involving autistic adults have often focused on negative outcomes and quality of life ratings. Aims This study provides a different viewpoint by examining the perspectives of autistic men who consider themselves to be successful. Methods Data were gathered from 10 men who shared their experiences and perceptions regarding their journey to achieve success. Self-determination theory provided a useful lens for examining the men’s narratives and understanding the factors that led to their success. Results Analysis of interviews revealed four main themes: (1) being my own self, (2) a competent professional, (3) solving problems in a neurotypical world, and (4) relating and connecting. These themes reflect the men’s perception of their own self-determination including their autonomy, competence, and relatedness with others. Conclusions The men’s sense of success was derived from their ability to achieve competence in their work, act without help or influence from others and demonstrate a high level of self-awareness and self-reflection. Despite this, many continued to experience difficulty in the social areas of their lives. Implications: These findings suggest that self-determination theory may present an alternative and more positive means of enacting support programs for autistic individuals, and males in particular.

Little is known about the effectiveness of self-determination theory (SDT), a representative motivational theory, on exercise domain in older adults. This feasibility study used quantitative and qualitative approaches to evaluate the effectiveness of a 13-month group exercise program applying SDT-based motivational strategies on exercise adherence, physical fitness, and quality of life, and to explore factors affecting exercise adherence in South Korean older adults (N = 18). Exercise attendance rate was high (82.52%). There were significant differences in aerobic endurance (p < .001), lower body strength (p < .05), dynamic balance (p < .001), and perceived social functioning (p < .05) at 13 months compared with baseline. Factors affecting exercise adherence were related to the SDT-based motivational strategies. These results support the importance of health professionals applying SDT-based motivational strategies to exercise programs to help facilitate motivation for participation and to promote physical fitness and quality of life in older adults.

Investigações anteriores, desenvolvidas no contexto da educação física (EF), têm vindo a incorporar e testar vários pressupostos da teoria da autodeterminação (TAD). Porém, permanecem ainda várias lacunas nesta área (ex. impacto de um clima de suporte às necessidades psicológicas básicas no envolvimento das pessoas nas tarefas). Assim, este estudo transversal examinou um modelo motivacional baseado nos pressupostos da TAD e explorou a sua invariância entre géneros e ciclos de escolaridade. A amostra foi constituída por 1390 alunos Portugueses (52.5% raparigas; idade média, 15 anos) do 3º ciclo (12-14 anos) e ensino secundário (15-17 anos). Questionários validados internacionalmente foram utilizados para avaliar a perceção de uso de estratégias motivacionais, a satisfação de necessidades, motivações e envolvimento nas aulas de EF. As correlações bivariadas entre as estratégias percecionadas, necessidades básicas, motivações e as dimensões do envolvimento mostraram os padrões de associação esperados. As análises de mediação revelaram que os alunos que percepcionaram maior utilização de estratégias de suporte às necessidades básicas experienciaram níveis mais elevados de satisfação destas necessidades, o que, por sua vez, se associou a motivações mais autónomas e a níveis mais elevados de envolvimento nas aulas de EF. As estratégias percecionadas também se relacionaram positivamente com o envolvimento nas aulas via níveis mais baixos de amotivação para a EF (mas com menor poder explicativo). Na sua generalidade, as análises de invariância suportaram a universalidade da sequência motivacional proposta pela TAD. Este estudo dá suporte aos pressupostos da TAD e corrobora a sua aplicação no contexto da educação física, ampliando a evidência neste campo.Resumen. Las investigaciones basadas en los postulados la teoría de la autodeterminación (TAD) desarrolladas en el contexto de la educación física (EF) se han visto incrementadas. Sin embargo, aún quedan varias lagunas en la literatura (ej., impacto de un ambiente de aprendizaje de apoyo en el compromiso de los estudiantes). Como tal, este estudio transversal examinó un modelo de motivación basado en los principios de la teoría de la autodeterminación, y analizó la invarianza del modelo en función del género y del ciclo de estudios. Los participantes fueron 1390 estudiantes portugueses (52,5% mujeres: edad media = 15 años) del 3º ciclo de estudios (12-14 años) y de la enseñanza secundaria (15-17 años). Se utilizaron cuestionarios validados internacionalmente para evaluar la percepción de estrategias de motivación, las necesidades, motivaciones y el compromiso en las clases de EF. Las correlaciones bivariadas entre la percepción de estrategias de apoyo, la satisfacción de las necesidades, las motivaciones y dimensiones de compromiso confirmaron los patrones de asociación esperados. El análisis de mediación reveló que los estudiantes que perciben el uso de estrategias de apoyo mostraron mayor satisfacción de las necesidades, las cuales, a su vez se asociaron con más motivaciones autónomas y mayores niveles de implicación en las clases. La percepción de apoyo también se relacionó con la implicación en EF a través de los niveles bajos en la amotivación (aunque mostrando menor poder explicativo). Por último, la secuencia de motivación en general se mostró invariante en función del género y el ciclo de estudios. Este estudio apoya los presupuestos de la TAD y apoya su aplicación en el contexto de la educación física, ampliando la evidencia en este campo.Abstract. Prior research conducted in the context of school physical education (PE) has increasingly incorporated and tested several postulations of self-determination theory (SDT). Yet, there still remain several gaps in the SDT-related literature (e.g. impact of a need-supportive social context on one’s engagement in behaviors). As such, the present cross-sectional study examined a model of motivation based on the tenets of self-determination theory, and explored the invariance of the model across gender and education cycle. Participants were 1390 Portuguese students (52.5% female; mean age, 15 years-old) belonging to the 3rd (12-14 years-old) and secondary cycle of studies (15-17 years-old). Internationally validated questionnaires were used to measure need support, need satisfaction, motivation, and engagement in PE. Bivariate correlations between perceived strategies, needs’ satisfaction, motivations and engagement dimensions showed the expected patterns of association. Mediation analysis revealed that students who perceived the use of need-supporting strategies experienced greater levels of need satisfaction, which, in turn predicted autonomous motivation, which, in turn, linked to engagement in PE classes. Perceived strategies also related to PE engagement through reduced levels of amotivation (though showing lower explanatory power). Invariance analysis generally supported the universality of the SDT motivational sequence, across gender and cycle of studies. This study provides support for self-determination theory and corroborates the application of the framework to the context of school PE, extending research in this field.
